The invention discloses a needle cavity used for an anesthesia puncture needle. The needle cavity is characterized by comprising a cavity body, one end of the cavity body is fixed to a needle cavity base, and the other end of the cavity body is a needle outlet end. The needle outlet end comprises two needle outlets, the needle outlets comprise the first needle outlet and the second needle outlet, the first needle outlet is formed in the needle point part of the needle cavity, the needle point part is a needle outlet bent in an arc shape, and the second needle outlet is formed in the arc-shaped back face of the first needle outlet. The section of the cavity body is in a water drip shape and comprises two channels, and the two channels correspond to the first needle outlet and the second needle outlet respectively. In this way, two anesthesia catheters extend into the needle cavity at the same time, meanwhile, injection of anesthetics is performed, when the usage amount of the anesthetics for an operation is reached, the operation can be performed instantly, operation time can be shortened, and the success rate of the rescuing operation can be increased.

The invention discloses a novel scatheless anesthesia catheter, comprising an inner tube, wherein a scale mark and an X-ray developing line are arranged at the outer wall of the inner tube; an outer tube is sleeved outside the inner tube; a soft head is arranged at the end part of the outer tube; and the soft head is fixedly connected with the outer tube.
